ABSTRACT:
There is disclosed an electronic control system for controlling a carburetor equipped with a slow-main system solenoid valve and an enrichment system solenoid valve of different control ranges whose openings are electromagnetically controlled to control the air-fuel ratio of a mixture supplied to an internal combustion engine. The control system calculates, based on signals representative of the engine operating condition including engine temperature, the duty for control of the slow-main system solenoid valve in accordance with the air-fuel ratio required for various engine operating states. When the value of this duty exceeds a predetermined value, the enrichment system solenoid valve is added to the slow-main system solenoid valve to accurately control the air-fuel ratio over a wide range.
